Embodiment Construction

[0034]Parts and values which are the same, or correspond to one another, are provided with identical or corresponding references.

[0035]FIG. 1 shows, in a schematic block representation, an illumination apparatus 1 which is formed as aircraft interior illumination. The illumination apparatus 1 comprises a multiplicity of n illumination units 2, each illumination unit 2 being assigned an LED arrangement 3 having at least one LED group 4, which comprises a plurality of individual LEDs 5. Furthermore, each illumination unit 2 comprises a supply device 6, which constitutes the energy supply of the LED arrangement 3.

[0036]The LED arrangements 3 are, for example, distributed in the aircraft interior and are used to illuminate the passenger cabin. All the LEDs 5 of one of the LED groups 4 are of the same design and / or have the same colour. In the illumination apparatus 1 shown in FIG. 1, all the LED groups 4 are formed with the same design as one another.

[0037]The illumination apparatus 1 c...

Abstract

The invention relates to an illumination apparatus having at least a first and a second illumination unit, wherein each of the illumination units comprises an LED arrangement and a supply device for supplying the LED arrangement, each of the LED arrangements comprising at least one LED group having a multiplicity of LEDs and the LED groups of the LED arrangements being similar, and having a control device for driving the at least two illumination units with a common nominal dim drive value, the nominal dim drive value driving the illumination units in such a way that the similar LED groups of the illumination units are operated in a dim mode. The invention also relates to a method for operating the illumination apparatus in the dim mode.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to an illumination apparatus having at least a first and a second illumination unit, wherein each of the illumination units comprises an LED arrangement and a supply device for supplying the LED arrangement, each of the LED arrangements comprising at least one LED group having a multiplicity of LEDs and the LED groups of the LED arrangements being similar, and having a control device for driving the at least two illumination units with a common nominal dim drive value, the nominal dim drive value driving the illumination units in such a way that the similar LED groups of the illumination units are operated in a dim mode. The invention also relates to a method for operating the illumination apparatus in the dim mode.DISCUSSION OF THE PRIOR ART[0002]LED illuminations are used in view of weight and of energy consumption as modern alternatives to conventional illumination means, for example incandescent lamps. However, the energy su...
